management programs (such as an electronic calendar and address book) typically found in a

touch screen interface for accessing its calendar, address book, calculator, and other functions. As

third-generation (3G) mobile phone networks in 2001. (39) 3G, most mobile phones could send

takes place at bit-rates (40) for sending and receiving photographs, video clips, music files, e-mails,
and more.
